MBRC Planning Scheme - Drainage Investigation Area (DIA)

In some locations in the Moreton Bay Region, there may be potential for infrastructure solutions, works and/or building design to help reduce the extent and degree of flood risk, while facilitating appropriate redevelopment/intensification of an area. These areas are identified as a Drainage Investigation Area (DIA). In some cases the works required will involve the introduction of additional on-property infrastructure that will need to be implemented at the time of redevelopment. Further studies are required in these locations prior to development being undertaken to identify practical and cost-effective flood risk mitigation options.

How are the Drainage Investigation Areas identified?

Drainage investigation areas are located in areas where Council has identified a desire for redevelopment or intensification through the MBRC planning scheme. It is recognised that the existing development potential is constrained as a result of the current flood risk present on a property or group of properties. DIAs are located in areas identified in the General residential zone - Next generation neighbourhood precinct or General residential zone - Urban neighbourhood precinct within the MBRC scheme as well as being located in a high and/or medium risk area as per the Flood hazard overlay.


Council has identified 15 Drainage investigation areas across the region. These are located in the suburbs of:

  • Albany Creek
  • Burpengary
  • Caboolture
  • Clontarf
  • Deception Bay
  • Margate
  • Redcliffe
  • Rothwell
  • Scarborough
  • Woody Point

The Drainage Investigation areas were amended by Tailored Amendment No.1 (2019).

Drainage Investigation areas are available for view in section 8.2.2 Flood hazard overlay code of the MBRC Planning Scheme.

What is Council doing in these locations?

Council recognises these existing urban areas provide logical locations for re-development and intensification, however due to limited capacity of stormwater and flood conveyance networks, these areas have unacceptable levels of current climate flood risk and cannot be developed in line with published land use zoning. 

The Drainage master plan will identify the most appropriate planning and building controls (such as earthworks, flood levels and building design) and/or infrastructure solutions (such as detention basins and piped drainage) to reduce the existing flood risk present in each of these locations.

The implementation of the Drainage master plans will be achieved through the planning scheme including working with those wishing to undertake development in these areas. Council may look to utilise its works program to support works where infrastructure solutions are identified as being an appropriate mitigation measure. It is very likely that the works required will involve a number of stakeholders to contribute to a solution that supports redevelopment in these areas. 

Implementation of the Drainage master plan will require further detailed design, and consultation with stakeholders to ensure a coordinated approach to the staging of development and flood risk mitigation works elements within the plan.
